AUXILIARY STORAGE TANK AND CONDENSER FOR MOTOR VEHICLE COOLING SYSTEMSFiled Dec. 20, 19so Inventor Patented Aug. 23, 1932 UNITED STATES PATENTOFFICE AUXILIARY STORAGE TANK AND CONDENSER FOR MOTOR VEHICLE COOLINGSYSTEMS Application filed December 20, 1930. Serial No. 503,796.

The present invention'relates to new and useful improvements in internalcombustion engines, and more particularly it pertains to a new and novelimprovement in connecd] tion with the cooling system thereof.

It is one of the objects of the present invention to provide a storagetank or receptacle whereby an auxiliary supply of cooling fluid for thecooling system of the internal to combustion motor of an automobile maybe at all times retained on hand. g

It is a further object of the invention, so to construct the apparatusthat its action will be automatic, that is to say that vapor arisingwithin the cooling system of the motor will be conveyed to the auxiliarytank where means is provided for its condensation and wherein the liquidcondensation may be automatically returned to the cooling system un- 29der certaiifconditions.

It is a still further object of the invention to combine with theauxiliary tank, a suitable. condenser preferably in the form of a coilthrough which the vapor circulates,

25 which coil is exposed to atmosphere and has one end open thereto.

With the above and other objects in view, reference is had to theaccompanying drawing, wherein,

Figure 1 is a longitudinal sectional view of the hood portion of a motorvehicle showing the motor thereof in dotted line, the cooling system infull lines partially in section and a device constructed in accordancewith the present invention in elevation, and;

Figure 2 is a detail vertical sectional view on an enlarged scale of adevice constructed in accordance with the present invention.

Referring more specifically to the drawing,

the reference numeral 5 designates the hood of a motor vehicle, 6 thedashboard thereof tank 12, and it may be suitably mounted in any desiredposition it being herein illustrated as carried in brackets or the like13 secured to the front face of the dashboard 6.

A pipe or tube designated 14 connects-said receptacle or tank 12 withthe lower end of the over flow tube as at 15 in Figure 1. It will beapparent that liquid or vapors which would ordinarily be discharged fromthe over flow tube 10 will be conveyed by means of the pipe or tube 14to the receptacle 12 instead of being discharged from the radiator ashas been heretofore the practice.

Mounted within the tank or container 12 there is a floating partition 16and said 'partition 16 divides the tank or receptacle 12 into a fluidcompartment 17 and an atmosphere compartment 18 the size of thesecompartments varying with the quantity or volume of liquid contained inthe liquid compart-.

ment 17. p

The tank or receptacle 12 has a removable cover 19, and carried by thecover 19 there is a condensing coil 20. One end of this coil is attachedto the removable cover 19 as at 21 and the other end such as 22 is opento atmosphere. p 1

Thus it will be seen that as fluid enters the tank or receptacle 12 anyvapors arising therefrom will pass around the float partition 16, itbeing slightly smaller in diameter than the diameter of the tank, intothe coil where they will be condensed into liquid form and thecondensate will drain through the end 21 of the coil into the receptacle12.

A gauge such as a transparent tube 25 may be employed to give a readingas to the volume of liquids contained in the tank or receptacle 12.

From the foregoing description it will be apparent that as the coolingfluid in the radiator and other portions-of the cooling system expands,the over flow or excess volume will be passed through the over flow tube10 and the pipe or tube 14 to the tank or receptacle 12. Any vaporsarising therefrom will pass into the condensing tube 20 and will becondensed returning to the tank or receptacle 12 in liquid form. As themotor ceasesoperation, and the fluid in the cooling system is lowered intemperature, a partial vacuum will be produced in the cooling system,particularly in the top of the radiator 7 and this partial vacuum willserve to withdraw the condensed fluidfrom the tank or receptacle 12again into the radiator for the purpose of supplying suflicient coolingfluids to the motor whenthesame is again placed in operation.

It is of course to be understood that in order to obtain the desiredresult in a system as above described,- the cap which closes theradiator and designated 30 in Figure 1 must be airtight, and that theentire system must have no communication with the atmosphere other thanthat above the level of cooling fluids in the tank or receptacle 12.

. While the invention has been herein illustrated in .what may be termeda preferred form, it is to be understood that the invention is not to belimited to the specific con-- struction herein shown, and that it may bepracticed in other forms without departing from the spirit thereof andthe scope of the appended claim.

Having thus-described the invention, what is claimed as new, and what itis desired to secure by Letters-Patent of the United States, 1s; a

In combination with the radiator of an automobile and having an overflowpipe, a

receptacle, a pipe connecting said overflow pipe with the bottom of saidreceptacle, a top for closing saidreceptaele, and acondens'ing coilcarriedby said top, said condensing coil having one end open toatmosphere, and

its other end in communication with the interior of said receptaclewhereby fluid of con densation may drain from the condensing coil tosaid receptacle.

' In testimony whereof I aflix my signature.
